德国WIKA公司生产了一系列特殊的压力传感器。过去在挤压机及注塑机加工时,对高温塑料的压力测量一直是塑料加工的难题之一。WIKA公司现在生产的这一系列特殊压力传感器可以使用到材料温度达400℃。这种压力传感器的测量范围为:0～50巴至0～2000巴,可提供的传感器精度为:0.5％和1％,其输出可为电压,也可为电流。目前销售的有4 Germany WIKA company produced a series of special pressure sensors. In the past in the extrusion press and injection molding machine, the pressure on the high temperature plastic measurement has been one of the problems of plastic processing. The series of special pressure sensors WIKA now produces can be used up to a material temperature of 400 ° C. The pressure sensor has a measuring range of 0 to 50 bar to 0 to 2000 bar and offers sensor accuracy of 0.5% and 1%, the output of which can be either voltage or current. Currently there are 4 sales
